Although it has been verified that sEHis can protect the ischemic myocardium of mice with MI through the SRF and the PI3Kα/Akt/GSK3β pathway, thereby reducing the occurrence of an ischemic arrhythmia, we did not measure the action potential duration, current density, or other related indicators of arrhythmia in the overall animal experiment. The gene discussed is GSK3B; the disease is cardiac arrhythmia.
